I often name files using a convention such that I incorporate a version number at the end, similar to Some Deliverable - v0.1.docx
. Sometimes when colleagues make changes and send back revised versions they will update that version number, but they will also replace the extra period with a space, such as Some Deliverable - v0 2.docx
.
This happens often enough, with a wide enough variety of colleagues, that I wonder: Is there still a danger in naming a file with multiple periods? Are my colleagues being overly cautious or taking valid precautions? And if it is a valid precaution, under what circumstances would a file with multiple periods cause problems?
If this is a holdover from pre-Windows 95 days or something then I'm not worried, but if this is something that, for example, causes problems when sharing a file with a Mac user – or an iPad user? – or a Linux user then I'll change my ways and stick to one period in a file name, before the extension.
5I never had any problems in using multiple dots in file names. Not under GNU/linux (ext2 fs), nor on FreeBSD, nor on windows (FAT32 and NTFS). Accessing such files via a samba network always worked. I strongly suspect that there is no problem. – Hennes – 2012-07-18T19:12:48.333
2Especially considering that Linux and OS X users have dealt with files named
something-v1.23.4-something.tar.gz.sig
for years without any troubles... – user1686 – 2012-07-18T19:13:59.190I agree that there is no problem per se, but if I had my druthers, I would make all users use keyboards with nothing but the letters of the alphabet and a period. Not even a space bar or a shift key. – EBGreen – 2012-07-18T19:14:15.810

I've seen warnings about files having multiple extensions, but I don't remember if that was Windows or a browser or what. I haven't used any version of Windows newer than XP on a daily basis, so I don't know if there's something in the additional security layers of Vista/7 that might be complaining. As @grawity said, Linux and OS X users have had multiple periods in their files for years. – ND Geek – 2012-07-18T19:20:21.717
Meh...an impossible dream I know. Not intended to be a troll. Just years of writing regexes and string parsing routines that are more complex than they would be if users were restricted to my ideal keyboard. I would of course get a full keyboard as per the double standard that is the perogative of IT professionals everywhere... – EBGreen – 2012-07-18T19:27:50.243
1The multiple extensions warning was for windows. With the default windows [explorer] configuration "some_virus.jpg.exe" would show up as a seemlingly harmless picture file named "some_virus.jpg". – Hennes – 2012-07-18T20:51:59.367
@Hennes, except that with that default configuration, the ".jpg" extension shouldn't have been visible, so when you see it, it's a sign that it's not the real extension. – Wyzard – 2012-07-18T23:45:18.697
Aye. Should have. All the people who failed to notice that and messed up their computers came running to me (well, to IT) to fix their computers. Many of them bright enough to have realized something was odd if only one file showed an extension. – Hennes – 2012-07-18T23:48:37.197
1@Hennes: It could be that some didn't notice this because they don't know whether their mail program honors the "hide extension" setting or not when listing attachments. – user1686 – 2012-07-19T10:21:46.293
